Direct X-ray detection CCD for astrophysics and planetary science

Abstract

We can measure X-ray photon energy precisely using a low-noise readout system with an X-ray Charge Coupled Device (CCD). Astronomical X-ray CCDs have a deep depletion layer and are employed with X-ray optics. We have developed such CCDs for X-ray use that is employed both in the sample-return satellite, "Hayabusa", and in the MAXI on the Space Station. A new type of CCD with a scintillator is introduced. We will employ our technique in laboratory applications as well as astronomical applications.
